Many thanks to YouTube member nao55akita, who found my Tsukuba Circuit videos and put one on his favorites list. He also had these BCNR33 GT-R TV Commercials.
初期BCNR33 （BCNR before first minor change)
BCNR33, IRON CHEF style! 料理の鉄人がBCNR33CM！
後期version of BCNR (after second minor change)
Here is the longer version!
this really isn't a commercial for the R33 GTR, per se, but...
This is a Nissan car...
ほかにありませんでしょうか？Any others out there??
